ture, of which the following is a specifi-.

cation.

This invention has as its object to provide a novel and highly eflicient composition for application to the glass panes of wind shields on automobiles or to anyother glass panes, exposed to the elements, for the purpose of prevent' the accumulation of rain, mist, snow and s set upon the exposed surface thereof so that the pane, in inclement weather, will remain as transparent as though not exposed to the elements.

Another object of the invention is to rovide a composition, in plaste form, w 'ch may be convenient] app 'ed to the exposed surface of the win shield panes in such a manner as to form upon the pane an invisible film of the composition.

The composition embodyingthe invention consists of an intimate mixture of the following ingredients in approximately the proportions stated Soap -10 ounces av. Glycerine 2 ounces av. Water glass 2 ounces av. Water 5 to fluid ounces. Methyl violet ...10 to drops.

Oil of cloves ..10 to 30 drops.

which might be left remaining after the preparatory cleaning of the glass, and also to assist in giving body to the composition. Glycerine, as is well known, serves to prevent the accumulation of water, moisture, mist, snow and sleet, upon a glass surface to which it is applied, and it serves this function in the present composition, and likewise as a medium to revent caking or hardening of the composition and thus cause the same to maintain its pasty consistency. The waterflass is likewise employed for the purpose 0 maintaining the original consistency of the compos1tion, and it serves the further purpose of adhering to the lass surface to which the composition is app ied, to a sufficient degree to insure of a thin and substantially invisible film of the com sition being retained upon the surface of the glass for an indefinite period of time. The incorporation of a suitable volume of water in the composition serves the purpose of partially dissolving the sea and likewise constitutes a medium where y the consistency of the composition may be varied until the desired pastiness is obtained. The methyl violet and the oil of cloves are employed respectively as coloring and scent imparting mediums.

In the use of the composition, a suitable quantity thereof is applied over the exposed surface of the wind shield or other glass pane, as thinly as possible, and the excess quantity of the composition is then removed by rubbing the surface of the glass with a 0 0th. This latter step, however, does not com letely remove the composition for due to the presence of the water glass therein, a thin and substantially invisible film of the composition is left upon the surface without in any way impairing the transparency of the glass pane.

It will be understood of course that I am not to be restricted to the precise formula above outlined, but may employ equivalent ingredients and may vary the proportions of the ingredients within reasonable limits.

Having thus described the invention, what I claim is:

1. A coating paste to prevent the accumu- 100 lation of moisture upon the exposed surface of glass panes comprising a mixture of soap, glycerine, water glass, and water.

2. A coating paste to prevent the accumu- 5 lation of moisture upon the exposed surface of glass panes comprising a mixture of soap,

glycerine, water glass, and water, in about the proportions of soap ten ounces av., glycerine two ounces av., water g1ass two ounces av., and water from five to fifteen 10 fluid ounces.

In testimony whereof I aflix my signature.
